plete description of the cash register to which the present invention has been applied. While the improvements set forth in this application are shown applied to a particular type of cash register illustrated in the parent application their utility by no means limited to this specific embodiment. The improvements are of such a nature that they may be applied in various modifications to many other kinds and principles of cash registers and accounting machines.

The principal object of this invention is to provide a plurality of individual totahzers for keeping separately the amounts of the receipts of di'rl'erent clerks, departments of store, or the different transactions that occur in a mercantile establishment.

The main object is to provide an improved type of totalizer selecting mechanism so that by a preliminary adjustment there may be established a co-operative relation between any one of said totalizers and a common totalizer operating means.

A further object is to provide improved devices for throwing the totalizers out of operative relation when certain special keys, such as, Paid out, Charge or similar keys are operated.

ln the preferr d embodiment of the invention as disclosed in the drawings, the img: ovement which is effected by the present invention is the simplification of the mechanism iriually utilized for controlling the engagement of one of a plurality of totalizers. Machines of the general type to which the sent invention has been applied are usual- :rovided with connections from the main 63,695. Divided and this app1ication filed June 14,

one totalizer. In machines of the latter type, the engaging mechanism is frequently not only designed to select the totalizer in which it is desired to insert the entry of a particular item, but it is usually provided with addi tional means under control of certain special keys, such as, Charge and Paid out keys of a cash register, so that an item may be prevented from being entered into any of the totalizers. This function of preventing the engagement with the actuators of a totalizer vwhich has been selected, is known as a throwout function. According to the present invention the totalizcr engaging mechanism is adapted both to select one of a plurality of totalizers for engagement with the actuators and to cause a throwout function of the selected totalizer upon the operation of a special key.

In accomplishing this result a great simplification has been introduced by the present invention through the use of a single shiftable .and pivoted slide for both selecting a totalizer and providing the throwout function. The slide is normally adapted to be rocked, upon an operation of the machine. about a pivot at one end, and when so rocked it will normally cause the engagement of one of the totalizers. Operation of a totalizor selecting element, such as a clerks key, is designed to shift the slide by moving its pivotal point so that, during the subsequent operation of the machine, the first totalizer will not be affected but another totalizer will be rocked into engagement with the acuators. Still fur her movement of the slide by shifting the pivotal point still further by connections from a special manipulative means,

such as a Paid out or Charge key, will serve to completely disengage the slide from the operating mechanism. Thus, when the slide is in this position, none of a plurality of totalizers will be engaged with the actuators.

In order that a totalizer which is not intended for operation will not be accidentally rocked, a special detent element is placed under control of the selecting slide and this element willprevent the movement of one or another of ti totalizers. Suitable means is similarly provided to prevent the rocking of any totalizer when a throwout key has been operated.

In carrying out the present invention it has been found an advantageous feature to employ a single train of connections from all of the controlling keys to the single controlling slide. These connections may include a rock shaft extending across the clerrs and special transaction keys, so that a cam shoe may be pinned to the shaft, adjacent any of the desired keys, in order that pins carried by such keys may rock the shaft to different extents to either select a totalizer or perform a throwout function. By applying the principle of the totalizer control mechanism, disclosed herein, the system of selection and elimination of totalizers for engagement with the actuators may be very readily varied, so that if desired, two totalizers may be engaged at one time with the actuators, and one may be eliminated without eliminating the other, or both may be eliminated simultaneously.

Reference will now be had to the figures of the drawings, which, taken in connection with the detailed description which will follow, constitute a full disclosure of one form of the invention.

In the drawings:

Fig. 1 is a sectional view in elevation of the machine which is used for the purpose of illustration showing particularly the operating keys, the differential mechanism and the mechanism for controlling the engagement of the totalizers, together with the connections from the special keys for controlling the selection of the totalizers.

2 is a detail view of one of the elements of the totalizer engaging and selecting devices which is utilized for the pin'pose of locking the undesired totalizers in their normal positions.

Fig. 8 is a plan view of the machine showing the arrangement of the multiple totalizers, the totalizing engaging mechanism and their connections to the special keys for controlling the selection or disengagement of the totalizers.

The general construction and operation of the various features of the invention, as embodied in the illustrative machine, have been explained rather fully in the foregoing state ment of the objects of the invention. A detailed description will now be iven of the essential elements of the machine embodying the invention defined by the appended claims.

The machine which is used for the purpose of illustration is of the key operated type of cash register and is provided with the usual series of operating keys, including amount keys and a number of special keys which will be later described.

The machine, as disclosed, is provided with a plurality of banks of amount keys butohviously the capacity of the machine and the designation of the amounts may be varied to suit the particular use to which the invention is put. The operating keys, as shown in 1, are all mounted on a transverse shaft 21. and the keys 're normally maintained with their forward operating ends elevated by means a weighted bail 22 extending across the tops of all the keys in rear of their pivots, the bail having a plurality of arms Xtending forwardly and pivoted about the key shaft 20. Depression of the forward end of any key will serve to elevate the weighted bail 22 and carry the upper surface of the latter substantially into engagement with the under cut-out surface of a key coupler 23. At the same time, an upper surface 24 toward the rear end of the key will engage the under surface of a pro- .1"C -14 v ett ng n p 2c of the key coupler Continued depression of the forward end of the key will then serve to elevate the key coupler 523 as well as the bail E22 and during this continued movement of the parts the lip 25 of the coupler will enter the notch 26 of the operated key.

The usual connections are provided from the key coupler to a main operating shaft within the machine, these connections coinprising a double rack member 2? (Fig. l) iaving sets of oppositely facing rack eeth adapted to alternately engage a pinion 253 (Fig. 3) mounted on a main operating shaft 29. As is well known in the art, the oscillation of the key coupler by the deg; sion andv return of one or more of the operating keys will serve to produce a full rotation of the shaft 29.

Adjacent to each of the amount keys and pivoted upon the key supporting she I t 21 is a cam plate 30 which is provided with an operating cam slot 31, the slots of the (-am plates of a series being graduated to effect an action of from 1 to 9 units. A suitable connection is provided between each key and its 111 8-1)- ciated cam plate, which may be in the form of a pin 32 mounted in each key and adapted to co-operate with a slot or notch in a forwardly extending arm of the plate. For each group of keys there is provided a segment frame comprising a pair of forwardly extending arms 3st, loosely mounted upon a transverse shaft 3: Between each pair of arms 31 and supported at its ends by the latter is a rod which imrmally in the open end of the graduated cam slots 31 of the se 'ies of cam plates 30 associated with the ope 'ating keys of a articular roup.

Each of the segment frames is movable with its related operating segment 8. niolmted on the shaft 35 and adapted to difi'ercntially adjust item type carriers and to operate the totalizing devices. The segments 37 are nested while the segment frames extend transversely of the machine and to transmit movement from the frames to the segments and suitable cross connections may be used and since this mechanism is not involved in the present application it is not shown or described in detail herein. One form which may be used is illustrated in the parent application above identified.

As the operating key of a particular group is depressed it will rock its associated cam plate 30 by means of the pin and slot connection 82, 38, and this cam plate, through its cam slot 31, will engage the rod 36 and rock the segment frame related to the key depressed an amount depending upon the value of the cam slot. Rocking of the segment frame will serve to rock the related actuating segment 37 in a counter-clockwise direction (Fig. 1) about the shaft 35. Upon release of the operated key after full depression, the parts described will return to their normal position.

The machine, as herein disclosed, is provided with a plurality of totalizers (two being shown) Figs. 1 and 3, which are adapted to selectively receive and accumulate the several amounts entered into the machine. The machine is so constructed that both of the totalizers are out of engagement with the actuating segments, but one of them is adapted to be normally rocked into engagement with the segments, at the beginning of the clown-stroke of the keys, while at the end of the down-stroke or the beginning of the return of the keys this totalizer is again disp-ngaged from the actuating segments. henever it is desired to add an amount in the other totalizer, a clerks or totalizer selecting key is operated and has the effect of causing the engagement with the actuators of the second or selected totalizer and preventing the engagement of the first mentioned totalizer. Provision is further made for preventing the engagement of either of the totalizers, whenever a special key of another character, such as one designating a special transaction, is depressed. The mechanism for accomplishing the above results will now be explained.

It will be noted that a pair of totalizer frames 38 and 88 are provided, and the totalizers will be hereinafter designated as the A and B totalizers respectively. Each totalizer frame is provided with a pair of supporting hubs 39 which are adapted to cooperate with a pair of studs 40, projecting from each of the pair of intermediate supporting frames 41 and 42. The totalizer frames 38 and 38 are each provided with a totalizer wheel supporting shaft 43 and 43 respectively on which are mounted a plurality of totalizer wheels 441. Ad acent each of the wheels of the totalizer, and secured to the latter, is mounted a pinion 451 which is adapted, at times, to co-operate with the associated driving segments 37 for the purpose of rotating the totalizer wheels to enter an item.

For the purpose of rocking the totalizers about their supporting studs 40 and in order to carry the pinions 451 into mesh with the actuating segments 37, a rockable and slidable plate 44 is provided. This plate is pivoted at,

45 to the upper end of an arm 46 secured to a shaft 47. The rearward end of the plate is provided with a forked projection 48, adapt ed to co-operate with a pin 49 carried by a rock lever 50, pivoted at 51 to the intermediate frame 41. A downwardly projecting extension of the rock lever carries a suitable pin or roller adapted to co-operate with the raceway of a ho); cam 52 secured to the main operating shaft 29. This cam is so formed that during the early part of the operation of the machine the rock arm 50 will be lowered,

while toward the beginning of the return 5 stroke of the keys and the coupler the arm will be elevated to its normal position again. It will be obvious that rocking of the arm 50 will impart a rocking movement to the plate 44, first in a downward or counter-clockwise direction and then upwardly in a clockwise direction. The upper rear corner of the plate 44 is provided with a square notch 53 which provides a rearwardly extending finger 54, which is adapted to normally engage the upper surface of the A totalizer wheel sup porting shaft 43 Similarly, toward the forward upper edge of the plate, a square notch 55 is provided and forms a finger 56 adapted to be brought over the upper surface of the B totalizer wheel supporting shaft 43 It will be noted that when the plate is in the position shown in Fig. 1 and the machine is operated to cause the arm 50 and the plate 44 to be rocked downwardly, the finger 54 will engage the A totalizer wheel supporting shaft and rock the pinions 451, carried by the latter, into engagement with the teeth of the actuating segments 37. However, if the plate 44 is shifted, in a manner to be described, slightly to the right of the position shown in Fig. 1, the finger 54 will be carried clear of the A totalizer supporting shaft 43 while the forward finger 56 will be carried over the B totalizer supporting shaft 43 so that upon a subsequent downward rocking of the plate 44 about its pivot 45 the B totalizer pinions 451 will be meshed with the actuating segments 37 while the A totalizer pinions will not be engaged. Movement of the plate 44 to bring about the reversal of action of the fingers 54 and 56, is produced by shifting of the pivot 45 through rocking of the shaft 47 and the arm 46 against the action vtotalizer and the disablement of the n the totalizer engaging mechanism may be completely disabled, so that neither totalizer w1ll be carried into engagement with the actuatmg segments. This result is brought about by the use of certain of the special transaction keys Each of these keys is provided with a pin similar to pin 59 which is adapted to co-operate with a cam shoe 63, also secured to the shaft .7. It will be noted that the cam formation of the shoe 63 is steeper than that of the shoe 61, so that operation of one of the special transaction keys 62 will cause a further movement of the shaft 47 and arm 46 than was caused by the clerk's or totalizer selecting key 58 This movement of the arm 4-6 under the influence of one of the keys 62,

which is prior to any rotation of the shaft 29, will shift the plate 44: forwardly until. its forked end 48 is disengaged from the pin 49. It will be obvious, therefore, that subsequent rocking of the arm 50 will have no effect upon the plate 4% and will not cause the engagement of the B totalizer even though the finger 56 will extend over its totalizer wheel supporting shaft 4:3

Suitable mechanism is provided and associated with the plate for preventing the rocking of one or the other, or both, of the totalizers, when they are not intended to be engaged with the actuating segments. The means, illustrated, for accomplishing this purpose, as best shown in Fig. 2, comprises a detent plate 64 pivoted at 65 to the intermediate supporting frame 41. A suitable connection is provided between the plate 44 and the detent plate (34-, which, as shown, takes the form of a pin 66 extending from the plate 44 into co-operation with a slot 67 in the deteut plate 64. In the normal position of the parts a detaining surface 68 of the detent plate is in engagen'ient with the under surface of the B'tota1izer wheel supporting shaft 43 and thereby eifectively prevents the rocking of the forward totalizer frame during a normal operation of the machine. However, when the plate 44: is shifted forwardly, under the influence of a clerks or totalizer selecting key 58 therefore 68 will be car ried away from the shaft 43 while, at the same time, a surface 69 of the plate 64; will be carried under the A totalizer wheel supporting shaft 43 Consequently, upon an operation of the machine in which the clerks key 58 has been depressed, the A totalizer will be positively locked against rocking into engagement with the actuating segments,

while rocking of the B totalizcr frame will be permitted. lVhen the plate 6% is given the additional forward movement, under the influence of a special transaction key 62, a surface 70 (Fig. 1) of the plate will be carried over a stud 71 extending from the side of the intermediate supporting frame 41. During an operation of the machine, therefore, in which a key 62 has been operated, the pin and slot connection 48, 4-9 will not only be disabled, but rocking of the plate l l vill be positively prevented by the engagement of surface 70 with the pin 71 and the lower edges of the square notches 53 and 55 with the und r surfaces of the pair of shaft 4 3 and 43;, respectively.

It will be obvious that by varying the normal relationship between the pair of shafts 43 and 413 and the engaginglingers 5-Zland 56 of the plate at, as well as the detaining surf cos 6S and 69 of the detent plate (34, the foregoing totalizer engaging mechanism may be readily modified to adapt it for use in a variety of systems of accounting.
